3 foods that can improve kidney function

The kidneys play a vital role in our body, filtering waste from the blood. Kidney health is crucial because kidneys filter waste and excess fluids from the blood, maintaining fluid and electrolyte balance, and regulating blood pressure. What we eat has a significant impact on kidney health. Dr. Eric Berg, a chiropractor and nutrition author, has now shared three foods that can improve kidney function. Let’s take a closer look.

Cucumbers

Keeping the body hydrated is crucial for kidney health. Dr. Berg suggests incorporating cucumbers into the diet. Cucumbers have 95% water content, which means they provide additional hydration. This water content can help in flushing out waste products from the kidneys, like creatinine and uric acid. Among the other water-rich vegetables, cucumbers are one of the lowest in calories. This means you can munch as many, without worrying about your weight loss goals. You can add them to salads or prepare cucumber-infused water to improve hydration levels in the body. You can also grate them and add Greek yogurt to it for a yummy snack.

Lemon

Second on the list is lemon. Yes, when life gives you lemons, make lemonade and boost your kidney function. The high Vitamin C and citrate content in lemon plays a significant role in reducing the risk of kidney stones. Studies have shown that drinking half a cup of lemon juice concentrate diluted in water each day, or the juice of two lemons, can increase urine citrate and likely reduce the risk of kidney stones. Squeezing fresh lemon juice into water or tea is a simple way to harness these benefits. Regular consumption may also help to lower uric acid levels, which can contribute to kidney strain when elevated. However, people who have acid reflex or sensitive stomach may have to consult a doctor before incorporating lemon into daily diet.

Parsley

Yes, that’s right. This humble herb has protective effects on the kidneys. The antioxidant properties of parsley help reduce oxidative stress, which is crucial when it comes to kidney diseases. Parsley contains several flavonoids, such as apigenin, luteolin, and quercetin. These compounds are known for their potent antioxidant and anti-inflammatory properties. A 2024 study found that parsley can reduce oxidative stress, improve metabolic biomarkers, enhance renal function, and inhibit the growth of various bacterial and fungal strains.

This herb also has potential in preventing and managing kidney-related disorders, infections, and other chronic conditions associated with oxidative damage and inflammation. Another 2017 study in rats with kidney stones found that those treated with parsley had decreased urinary calcium and protein excretion. An increased urinary pH and urination were also reported in the rats fed with parsley regularly and consistently.
